ABAP Freak Show – Aug 5th – ABAP OO Tutorial Part 5

by on August 5, 2009 at 12:48 pm

In this final entry in the 5 part ABAP OO series, we examine examples of how SAP puts the techniques that we learned in the previous 4 sessions to work within the standard code that they deliver to customers. We start by looking at the CL_BCS classes for sending email. CL_BCS* serves as a perfect example of the use of Persistent Objects and Polymorphism. We also look at the functionality behind the new ABAP Code Completion feature in the ABAP Editor. This block of code uses Persistent Objects, Inheritance/Polymorphism, Exception Classes, and MVC structured Classic Dynpro.

You can also download all the source code from all 5 tutorials. Just be sure to look at the ReadMe.pdf file for important tips on installing the source code.

ABAP Freak Show – July 22nd – ABAP OO Tutorial Part 4

by on July 22, 2009 at 2:37 pm

This is part 4 of the 5 part series on ABAP OO. In this part, we look at the special use case of Object Oriented technology and design techniques as they are applied to User Interface creation. Throughout all the ABAP UI technologies we study how MVC (Model View Controller) design can be applied. We look briefly at BSP and Web Dynpro ABAP and OO effects the overall design as well as specific features like UI element rendering and eventing. We close with an example of how you can adapt even Classic Dynpro and its PBO/PAI processing looks to a more Object Oriented MVC flow.
